Abstract

Provided is an oil or fat composition, which has an MCPD-FS content (ppm) of 13 ppm or less, the content being measured by a Deutsche Gesellschaft für Fettwissenschaft (DGF) standard method C-III 18(09), has a diacylglycerol content of 15 mass % or more, and is subjected to deodorization treatment.

Claims

exact text as granted — not AI-modified
The invention claimed is: 
     
       1. An oil or fat composition, which has a content of 3-chloropropane-1,2-diol forming substances (MCPD-FS) of 7 ppm or less, the content being measured by a Deutsche Gesellschaft für Fettwissenschaft (DGF) standard method C-III 18(09), has a diacylglycerol content of 15 mass % or more, and is subjected to deodorization treatment at a treatment temperature of from 120 to 205° C. and a treatment time of from 5 to 110 minutes,
 wherein the oil or fat comprises from 0.1 to 2 mass % of monoacylglycerol. 
 
     
     
       2. The oil or fat composition according to  claim 1 , wherein the diacylglycerol content is 20 mass % or more. 
     
     
       3. The oil or fat composition as defined in  claim 1 , wherein the diacylglycerol content is 30 mass % or more. 
     
     
       4. The oil or fat composition as defined in  claim 3 , wherein the diacylglycerol content is 50 mass % or more. 
     
     
       5. The oil or fat composition as defined in  claim 1 , wherein the MCPD-FS content (ppm), measured by a Deutsche Gesellschaft für Fettwissenschaft (DGF) standard method C-III 18(09), is 3 ppm or less. 
     
     
       6. The oil or fat composition as defined in  claim 5 , wherein the MCPD-FS content (ppm), measured by a Deutsche Gesellschaft für Fettwissenschaft (DGF) standard method C-III 18(09), is 1 ppm or less. 
     
     
       7. The oil or fat composition as defined in  claim 1 , wherein a content of elaidic acid present in a constituent fatty acid of an oil or fat in the oil or fat composition is 1 mass % or less. 
     
     
       8. The oil or fat composition as defined in  claim 1 , wherein in a constituent fatty acid of an oil or fat in the oil or fat composition, a ratio of a fatty acid having two double bonds, including a trans double bond, and having 18 carbon atoms to a fatty acid having two double bonds and having 18 carbon atoms is 4 mass % or less. 
     
     
       9. The oil or fat composition as defined in  claim 8 , wherein in a constituent fatty acid of an oil or fat in the oil or fat composition, a ratio of a fatty acid having two double bonds, including a trans double bond, and having 18 carbon atoms to a fatty acid having two double bonds and having  18  carbon atoms is 2.5 mass % or less. 
     
     
       10. The oil or fat composition as defined in  claim 1 , wherein the oil or fat comprises triacylglycerol in an amount of from 4.9 to 84.9 mass %. 
     
     
       11. The oil or fat composition as defined in  claim 1 , wherein the oil or fat comprises 5 mass % or less of a free fatty acid or a salt thereof. 
     
     
       12. The oil or fat composition as defined in  claim 11 , wherein the oil or fat comprises from 0 to 1 mass % of a free fatty acid or a salt thereof. 
     
     
       13. The oil or fat composition as defined in  claim 1 , wherein the deodorization treatment comprises a steam distillation under reduced pressure. 
     
     
       14. The oil or fat composition as defined in  claim 13 , wherein an amount of water vapor in the deodorization treatment is from 0.1 to 20 mass % with respect to an amount of the oil or fat. 
     
     
       15. The oil or fat composition as defined in  claim 13 , wherein a pressure in the deodorization treatment is from 0.01 to 4 kPa. 
     
     
       16. The oil or fat composition as defined in  claim 1 , which is subjected to a decoloration as a refinement of the oil or fat composition. 
     
     
       17. The oil or fat composition as defined in  claim 16 , wherein the decoloration comprises contacting at least one porous adsorbent selected from the group consisting of activated carbon, silicon dioxide and a solid acid adsorbent with the oil or fat composition. 
     
     
       18. The oil or fat composition as defined in  claim 17 , wherein the solid acid adsorbent is at least one adsorbent selected from the group consisting of acid clay, activated clay, activated alumina, silica gel, silica/alumina and aluminum silicate. 
     
     
       19. The oil or fat composition as defined in  claim 1 , wherein the deodorization treatment is applied in the final step of refining treatment. 
     
     
       20. An oil or fat composition, which has a content of 3-chloropropane-1,2-diol forming substances (MCPD-FS) of 7 ppm or less, wherein the content is measured by a Deutsche Gesellschaft für Fettwissenschaft (DGF) standard method C-III 18(09), has a diacylglycerol content of 15 mass % or more, and is subjected to deodorization treatment at a treatment temperature of from 120 to 205° C. and a treatment time of from 5 to 110 minutes,
 wherein the oil or fat comprises from 4.9 to 84.9 mass % of triacylglycerol. 
 
     
     
       21. The oil or fat composition as defined in  claim 20 , wherein the oil or fat comprises from 6.9 to 29.9 mass of triacylglycerol.
